Jupiter and Saturn

Jupiter is the largest planet in the solar system and has the fastest rotation. Saturn is the second-largest planet surrounded by rings of ice-covered rock. Both are gas giants.

Jupiter :

If oil the other planets were combined into one, its moss would be less than half of Jupiter`s. It is 1300 times larger than Earth.

Jupiter completes its rotation in less than ten hours. This speed results in strong winds and huge cloud bands. Strong storms develop when these bands of clouds meet. One hurricane known as the Great Red Spot has existed for over 300 years.

Saturn :

Like Jupiter, Saturn is made of hydrogen and helium gas. Saturn`s rotation is almost as fast as Jupiter`s. Saturn also has very strong winds reaching speeds that are 11 times faster than a hurricane on Earth. There are thousands of rings surrounding Saturn. Each ring contains pieces of ice and rock travelling in orbit around Saturn. The rings closer to the planet seem to hold larger pieces while the outer rings contain finer materials. Both Jupiter and Saturn have many satellites some discovered only very recently. Jupiter seems to have the most moons of any planet in our solar system — at least 62. Saturn has more than 30.
